Options

A. Zygomorphic epigynous
B. Zygomorphic hypogynous
C. Actinomorphic epigynous
D. Actinomorphic hypogynous.

Answer

To answer the question about the characteristics of disc florets of sunflower, we can break down the information as follows:

### Step-by-Step Solution:

1. **Understanding the Structure of Sunflower**:
- Sunflowers belong to the family Asteraceae and consist of many tiny flowers called florets.
- These florets are categorized into two types: disc florets and ray florets.

2. **Identifying Disc Florets**:
- Disc florets are located at the center of the sunflower's flower head.
- They are small and numerous.

3. **Symmetry of Disc Florets**:
- Disc florets exhibit actinomorphic symmetry, meaning they have radial symmetry.
- This allows them to be symmetrical around a central axis.

4. **Ovary Position**:
- The ovary of the disc florets is inferior, which means it is located below the other floral parts.
- This condition is referred to as epigynous, indicating that the ovary is fused with the hypanthium (the floral cup).

5. **Conclusion**:
- Based on the characteristics discussed, the disc florets of sunflowers are actinomorphic and epigynous.

### Final Answer:
The disc florets of sunflower are actinomorphic and epigynous.
